, s it known that I, EDWARD PossoN, a citizen of new and usefulImprovement inI Gar-Roofs; of` which thefollowingis a specification. nIn certain carroofscomprisingV-metallie sheets, it

to slide lh ngitudinally at the same time that they hold a strain uponthe nails, bolts or other fastening means inv the direction in whichtheir resistance is least as l@ne of the objects of my invention is toovercome this objection by providing the clips which are to be placed atthe ends of the standing seams with tongues which enter the seam andbear upwardly thereon. Thus, the seam will prevent any tilting of theclip.

A further object of 4the invention is to provide for the engagement ofthe tongue with the Wooden substructure to prevent movement of the clipin a direction longitudinal of the tongue.

. A further object of the invention is to provide a the clip out ofengagement sheets.

Other objects hereinafter more fully appea l In the accompanyingdrawings forming a part of this specification andwherein like symbolsrefer to like parts wherever they occur, Figure 1 is a sectional viewtaker'longitudinally of a seam 'tlough a portion of a ear roofnnear theeaves; Fig. 2is a lperspective view of the clip shown in Fig. l; Fig. 3is a transverse soc-4 tional vfhw through the clip and roof-sheets; Fig.4 is a sectional view similar to Fig.v1 but showing a modified clip;Fig. 5 is a perspective view of the clip shown in Fig. 4;.and, Fig. 6 isa transverse sectional view through the clip and roof-sheets shown inFig. 4.

The'invention has been illustrated by an embodimerite'mploying a roofhaving a wooden sub-'structure 1 and Aa metallic sheathing consisting ofsheets 2, 3 having interlocking rebent flanges forming a standing withthe body oi the roofscam; The, sheets extend down to the caves and havea vertical flange overhanging the eaves. Between the s ams, the edges ofthe sheets are fastened by angloyclips secured to the molding 5 of thecar. At i enter'the seam 4. The clip with all its parts is preferably asingle integral casting having, in effect', a groovearound the tongue toaccommodate the seam. The end of the seam bears against the base of theclip which thus'resists the tendency to downward Inovement of thesheets. The tongue bears upwardly upon lthe scam and thus the tilting ofthe clip and the con- -sequent tendency to -pull out its .fasteningmeans isprevented. In thisthe hood assists, though it is notindispensable, because the seam is cramped between manner as the tonguel0. It, however, depends be- This construction is advantageous becausethere is.'

often a slight relative movement of the roofsheets and of the lclips. Ifthese arein contact the protecting coating of the sheets may be rubbedoff and the sheet exposed to rust. flanges of the clip tends to holdwater in Contact with the worn places by capillary attraction` All thisis avoided when the flanges of the clips are held up by the'tongue. Thesame advantage may be secured for a rolled seam by so designing thetongue that4 it shall bear upon the bottom part oi' the seam and so holdthe flanges of the clips out of contact with the roof-sheets.

The tongue ll is provided on its lower lace with a plurality of smallprojections l2 which may be sunken in the wooden sub-structure oi' theroof and thus increase the resistance ot' the clip to. movementlongitudinal of the seam.

Obviously, my devicel is 'capable of modification within the scope ol myinvention and, therefore, l do Vnot; wish to be limited to the specificconstruction shown and described.

What I claim as my invention and desire to secure by Letters 'Patent is:l

1. A cnr ront' comprising n substructure, roof sheets joined by hollowsemns and fastening clips arranged to be secured to the side of the cui'und having tongues.projecting endwlsc luto said hollow seuulslongitudinally thereof.

The close contact of the sheets and l low seams longitudinally thereof.

2. A car roof comprising a sub-structure', roof sheets joined by hollowseams and fastening clips arranged to be secured to the side of the earand having tongues projecting endwise into said hollow seamslongitudinally thereof and arranged to have an upward and a downwardbearing iu the vertical plane of said seam.

3. A car roof comprising a sub-structure, roof sheets l joined by hollowseams and fastening clips arranged to be secured at the side of the earand having tongues projecting endwise into said seams longitudinallythereof and bearingupon said sub-structure, said tongues being providedon their lower faces with projections.

4. A car comprising a sub-structure, roof sheets joined by hollow seamsand'fastening clips arranged to be socured to the eaves and having hoodscovering the ends of said seams and tongues projecting endwise into saidhol- 5. A car roof comprising a sub-structure, roof sheets joined byhollow seams and fastening clips arranged to be secured to saidsub-structure and having hoods covering the ends of seams and tonguesprojecting into said seams, longitudinally thereof, the lower face ofthe tongue of each of said clips lying in a plane below the plane oftheA lower edge of the hood.

6. A car roof comprising a sub-structure, roof sheets ing upon saidsub-structure, the lower faces of said tongues 'being provided withprojections.

7. A clip for a car roof comprising a buse adapted to be secured to theeaves of the cnr, a hood projecting from said base and a tongue arrangedwithin su'd hood.

S. A clip for a car roof comprising a base adapted to be secured to theeaves of the car, a hood projecting laterally from said base and adaptedto tit over thc roof seam, and a tongue projecting laterally from snidbase and within said hood, said tongue being adapted to enter the hollowof said seam longitudinally thereof and the lower face o1' said tonguelying in a plane below the planiof` the lower edge of said hood.

9` A clip for car roofs comprising a buse, :1 hood projecting laterallyfrom said base and a tongue projecting laterally from said base andwithin said hood, the lower face ofsnid tongue being provided withprojections.

10` A car roof comprising a sub-structure, roof sheets joined by hollowseams, and n series of fastening clips nrranged to be secured to theside of the car each having a tongue projecting endwisc into said hollowscnlns longitudinaliy thereof.

In testimony whereof, l have signed my nnine to this specitication inthe presence of two subscribing witnesses this 23rd day of October,1905, at Chicago, illinois.
